BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof eaves ventilating metal member having a roof panel having a roof protruding slightly outside the outer wall.

[0002]

2. Description of the Related Art When a roof is constructed of a roof panel in which a plywood is attached to one surface of a wooden frame, the construction can be done in a short time and in a short time. Also, due to the site area and other factors, the length of the eaves overhanging is shorter, and so-called roofs with fewer eaves are increasing. Even in such a case, it is necessary to sufficiently ventilate the attic, and a structure in which the back side of the roof panel placed on the upper side of the outer wall is used as the ventilation port is often adopted.

[0003]

However, the conventional structure in which the rear surface of the roof panel of the eaves portion is used as the ventilation port has a problem in draining this portion. In other words, under the condition that there are enough eaves that can be seen in ancient Japanese style architecture, raindrops will not blow into the upper edge of the outer wall. However, as described above, in a roof with few eaves, a slight crosswind tends to cause raindrops to reach the upper side of the outer wall, which may cause a risk of wetting the attic. In order to avoid this, as shown in FIG. 4, a draining plate 10 also serving as a gable plate at the eaves tip of the roof 101.
A vertical gap 103 is formed by turning the lower side of the 2 toward the backside of the eaves and then erected, and a draining plate 106 on the upper side of the finishing material 105 of the outer wall 104 is arranged so as to form a narrow gap 107, and raindrop infiltration is performed. Is being prevented. However, both drainers 1
The construction times of 02 and 106 are different, the type of work is different, and the worker is naturally another person, and it is very complicated to perform smooth work management and process management.

Further, although the gap 107 is formed by vertical surfaces on both sides, the lower part of the eaves is a place where a strong vortex flow is generated, and rain gap intrusion can be completely prevented in the gap 107 formed by only the vertical surface. Have difficulty. An object of the present invention is to provide an eaves ventilating metal fitting that can reliably prevent raindrop intrusion, that is, drain water even on a roof with a short eaves tip, and that can be easily mounted and installed.

[0005]

The eaves ventilating hardware according to the present invention is the eaves ventilating hardware to be arranged at the eaves of a roof constructed by protruding the eaves to the outside of the outer wall and placing a roof panel on the upper side of the outer wall. A wall surface finishing material to be attached to the outer wall by providing a lower side of the eaves-side draining plate arranged on the outer surface of the eaves side and providing a side wall facing the outer wall with an eaves side partition wall forming a part of an air passage. An outer wall side partition wall forming another part of the air passage is provided on the outer surface of the outer wall side draining plate arranged on the upper side of the outer wall side draining plate, and the eaves side partitioning member is provided along with the arrangement of the eaves side draining plate and the outer wall side draining plate. The eaves side partition so that the air passage formed by the wall and the outer wall side partition wall forms a zigzag path extending in a direction orthogonal to the outer wall, and the eaves side partition is closed so as to seal both side ends of the air passage. And arranging the outer wall side partition wall.

[0006]

[Function] The eaves side partition wall provided on the side facing the outer wall extending the lower side of the eaves side draining plate on the outer surface of the eaves, and the outer wall side partitioning provided on the outer surface of the outer wall side draining plate on the upper side of the outer wall wall finishing material An air passage constituted by the wall is arranged so that both side ends thereof are sealed and a zigzag path extending in a direction orthogonal to the outer wall is formed. Thus, the raindrops in the airflow passing through the air passages are settled or separated by gravity when the direction is changed in the zigzag path, and are centrifugally separated to adhere to the wall surface of each partition wall. Therefore, the separated air drops, that is, the drained airflow reaches the ceiling from the back side of the upper roof panel, and ventilation is performed.

Is. In the figure, 1 is an eaves ventilation hardware, 2 is an outer wall, 3 is a roof, 31 is an eaves of the roof 3,
4 is the eaves side draining board, 41 is the side surface of the eaves side draining board 4,
42 is also the eaves side partition wall, 5 is the outer wall side draining plate, 5
1 is an outer surface of the outer wall side draining plate 5, 52 is also an outer wall side partition wall, 6 is an air passage, and 7 is a wall surface finishing material. FIG.
As shown in FIG. 1, the eaves ventilating hardware 1 of this embodiment has a roof 3 of a roof 3 constructed by placing a roof panel on the upper side of the outer wall 2 of the building.
It is arranged in 1 and is composed of two parts, an eaves side drainer 4 and an outer wall drainer 5. The roof 3 has the eaves 31 and the outer wall 2
The roof is ventilated through the gap 32 on the back surface of the roof panel that is slightly protruding outward from the roof panel and is located on the upper side of the outer wall 2.

The eaves-side draining plate 4 is arranged also on the outer surface of the eaves-side 31 also as a gable plate, but the lower side of the eaves-side draining plate 4 extends downward to face the outer wall 2 and forms a part of the air passage 6 at the eaves-side. A partition wall 42 is provided. The outer wall side draining plate 5 is arranged on the upper side of the wall surface finishing material 7 such as siding attached to the outer wall 2, and an outer wall side partition wall 52 constituting another part of the air passage 6 is provided on the outer side surface 51 thereof. The air passage 6 is a passage that connects the vicinity of the lower part of the eaves 31 and the gap 32 at the upper side of the outer wall 2, and has a relational form that forms a zigzag path extending in a direction orthogonal to the outer wall 2, as shown in the figure, and
Side walls 61 are provided at both end portions so as to seal both end portions of the air passage 6, and the eaves side partition wall 42 and the outer wall side partition wall 52 are arranged. Specifically, the outer wall side draining plate 5 with the outer wall side partition wall 52 having the form as shown in FIG. 2 is obtained by extrusion molding of aluminum, for example.

Eaves side draining plate 4 and outer wall side draining plate 5
Since each of them is nailed and fixed to the eaves tip 31 or the outer wall 2 as shown in FIG. 1, they are easily attached, and the air passage 6 is simultaneously formed by this attachment. That is,
With this structure, sheet metal work as in the past is unnecessary, and since it can be mounted by a general carpenter instead of a specialized sheet metal worker, process management, worker arrangement, etc. are significantly facilitated. The air passage 6 is a zigzag path, and the airflow passing therethrough repeats swirling. During that time, if the passing speed of the airflow is slow, the raindrops settle down due to gravity, or if the passing speed is fast, the raindrops are centrifugally separated and adhere to each partition wall surface. That is, reliable draining is performed here. In this case, draining can be performed without narrowing the interval of the air passages 6, the pressure loss to the air flow is small, and a large amount of ventilation is possible.

Next, another embodiment shown in FIG. 3 will be described. In this embodiment, the air passage 6 is arranged vertically, whereas the air passage 6 is arranged vertically in the case of FIG.
Therefore, the lateral member 33 having a triangular cross section is attached to the tip of the eaves tip 31, and the side surface 41 of the eaves side drainer plate 4 is erected so as to contact the vertical surface thereof. Therefore, as compared with FIG. 1, the eaves-side draining plate 4 has a vertical side 41 that is slightly wider than the eaves plate, and the appearance in the range from the eaves 31 to the eaves is slightly simplified. The rest of the configuration, operation, etc. are the same as in the above-mentioned embodiment, and a description thereof will be omitted.
